>>44010for me it's juggling, because it makes time go by so fast. I end up playing with my balls for hours and feel like barely any time has gone by.
Picrelated is my heart rate during juggling practice a few days ago.
So, just pick some kind of sport that you enjoy and don't mind doing for hours several times a week. Maybe for you it's kickboxing and hitting a sandbag for an hour or whatever.
Burpees are high-intensity but after doing 10 burpees it already gets boring.
